Criminal justice client rehabs can be considered like a far better option than jail time or significant fines for individuals who have already been convicted of any kind of alcohol or drug related crime. For instance, anyone who has been in prison for driving under the influence of alcohol or drugs may be eligible to receive rehab services for their problem rather than serving time in prison. The judge might even order that the individual receive rehabilitation, either alone or in addition to other sentencing. First-time offenders specifically are often given the chance to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they take advantage of it if it's an option. The idea behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into rehab than enforcement of other consequences. Much research has been carried out to find out how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients that do take part in rehab have better probability of remaining out of the system following rehab.
